Steel beam installation, rsj and structural alterations in Ruislip. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs RSJs and steel beams across Ruislip, from the mock-Tudor semis near Ruislip Lido to the 1930s and interwar houses that fill HA4. With over 30 years of structural experience in Hillingdon, we open up load-bearing walls safely, with every beam sized by a structural engineer and signed off by building control.

The interwar semi-detached houses across Ruislip were built with solid or cavity brick and internal load-bearing walls that carry the floors and roof above. When homeowners in HA4 want to join the kitchen and dining room, or open the hall into a reception room, that dividing wall usually cannot simply be knocked out. We install a correctly sized RSJ so the load transfers cleanly, keeping the 1930s house sound while the space below opens right up.
Every job starts with a structural engineer's calculation that sets the beam size, the bearing length and the padstone specification. We fit padstones at each end, typically a dense concrete or engineering-brick pad, so the steel bears without crushing the surrounding brickwork. Nothing is guessed on site. The drawings and calculations go to Hillingdon Council building control, and we book the inspections that the work requires as it progresses.
Before any brick comes down in a Ruislip property, we install temporary propping to hold the floors and roof above. Acrow props and strongboys take the load through the demolition zone, and we work in careful stages rather than dropping a wall in one go. This matters in the older interwar houses on generous plots around Ruislip, where floor joists and ceiling structure often bear directly onto the wall being removed.
Once the steel is seated on its padstones and packed tight, we transfer the load onto the beam, remove the propping and make good. Where the wall being altered is a party wall shared with the neighbouring semi, which is common in Ruislip's paired 1930s houses, the Party Wall Act applies and we help you serve the correct notices before work starts, so the process stays neighbourly and fully documented.
Ruislip homeowners choose GS Renovation because we treat structural work as engineering, not guesswork. Every beam is calculated, every padstone specified and every stage inspected by Hillingdon Council building control. With 30+ years across HA4 and neighbouring Uxbridge and Hillingdon, we prop safely, work tidily in occupied homes and hand back a stronger, more open house.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
FAQ
Every Ruislip project is priced on its own merits, as the cost of RSJ and steel beam installation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. As a rough guide, RSJ and steel beam installation in London runs roughly £1,500 to £4,000 for the beam itself on a single straightforward opening, covering supply, installation and building control sign-off; a full knock-through including taking the wall out, the structural engineer's fee and making good more typically comes to £2,500 to £6,500 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
A straightforward Ruislip project can be done in a couple of weeks, while a larger RSJ and steel beam installation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Removing a load-bearing wall in Ruislip does not normally need planning permission, but it always needs building regulations approval, a structural engineer's calculations and building control sign-off. Where the wall is shared with a neighbour, the Party Wall Act may also apply. We manage all of it.
Yes. A large share of Ruislip's homes are 1930s and interwar properties, and we renovate them regularly. We plan each RSJ and steel beam installation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Yes. Removing a load-bearing wall in a Ruislip house is structural work governed by building regulations, so it needs Hillingdon Council building control, not planning permission. A structural engineer sizes the RSJ and specifies the padstones, and building control inspects the work. If the wall is shared with your neighbouring semi, the Party Wall Act also applies and notices must be served first.
